NCF Clear Line USB Plug-in Noise Filter (Ea)

The NCF Clear Line series are the ultimate audio-grade passive optimizers, designed specifically for enhancing playback performance of source components and preamplifiers. These innovative devices, available in a variety of connector types bring the remarkable benefits of NCF technology to any audio or video system, improving sonic performance and overall clarity. 

Each NCF Clear Line model is a compact and passive device which plugs directly into a component. Furutech's proprietary NCF formula draws and dampens vibrations from within, effectively eliminating electrical and mechanical resonance. These devices significantly lower the noise floor and improve signal-to-noise ratio (SNR), creating an immersive and engaging listening experience.

How To Use
This couldn't be easier! Simply insert an NCF Clear Line device into any available port in your gear. The improvement in performance is remarkable. You will immediately notice an improvement in soundstage depth and focus that continues to improve as the device starts to settle down. Furutech recommends allowing the unit to settle for at least 24 hours for best results. The NCF Clear Line improves harmonics and balance of sound, increasing transparency, reducing high-frequency noise and enhancing overall dynamic contrast. You'll hear deeper black backgrounds and improved clarity.

24k Gold-Plated Nonmagnetic Connectors
A specially engineered 24k gold-plated copper alloy EMI shield incorporated into the connector to provide more stable, clearer, and more accurate audio transmission. The excellent conductivity of gold ensures more stable, accurate signal transmission, and consistency of audio signal delivery. Reduced Electromagnetic Interference (EMI) is essential for avoiding interference from electromagnetic noise in the surrounding environment. 

Electrolytic Capacitor
Furutech's electrolytic capacitors are engineered to optimize the acoustic performance of your devices. Furutech conducted extensive testing to select the ideal type and specifications of capacitor to elevate sound quality to its highest potential. The outer layer of these electrolytic capacitors is coated with a high performance silver-colored special damping treatment, effectively suppressing unwanted vibrations, and enhancing sound clarity. Additionally, these capacitors feature advanced tuning technology designed to eliminate any noise interference originating from the equipment's output terminals, ensuring an unparalleled sound experience. 

Nano Crystal Formula (aka NCF) 
This is the ultimate electrical and mechanical damping material. Developed by Furutech, NCF is a proprietary crystalline compound blended with ceramic nanoparticles and carbon powder. This process creates a remarkable material with multiple benefits: First, NCF generates negative ions to eliminate static charge build-up. Second, NCF converts thermal energy into far-infrared light, a remarkable innovation allowing the material to run cooler, even during the most demanding of passages. Third, NCF has excellent damping properties, thanks to the “piezoelectric effect” of the NCF material. Found exclusively in Furutech’s top offerings, NCF is a game-changing material and its sonic effect is undeniable; superior resolution, clarity and dynamics, with deep-black backgrounds and a purely natural tonal balance.

Two-Stage Alpha Process of Cryogenics and Demagnetization
For the first step in the Alpha Process, Furutech developed a low-temperature two-stage cryo process which significantly improves every facet of audio and video performance. The treatment begins during the manufacturing process with a deep, conditioning cryogenic freeze of all metal parts. Using high-end refrigerants (liquid N2 or Helium) Furutech drops the temperature to between -196℃ to -250℃. The treated parts change their molecular structure at these extremes relieving internal stress. The molecules bond together more tightly and the overall structure becomes more stable. This improves electrical conductivity and thus power & signal transfer. 

Step two of the Alpha Process exposes these same parts to Furutech’s patented Ring Demagnetization treatment. Ordinary high-power magnets used for this purpose can increase magnetic effects; leaving some areas more magnetized than others. The Ring Demagnetization treatment uses controlled attenuation to eliminate magnetization across the entire part delivering a substantially more vivid and wide bandwidth improvement. Ring Demagnetization further enhances conductivity of all treated materials. Every metallic part used in a Furutech product goes through the Alpha Process treatment to keep connectors, conductors, and other metal parts perfectly stress-free, stable, and highly conductive.
